💩 What Your Guinea Pig's Poop Tells You

Droppings are a daily health readout. What is normal, what is not, and when to worry.

It is not glamorous, but a guinea pig's droppings are one of the clearest early signals of health. A healthy pig produces a lot of them, so a change in number or shape is worth noticing.

Normal

Lots of firm, oval, evenly-sized droppings, medium brown and dry. A pig on good hay poops constantly, that is exactly what you want to see.

What changes mean

Fewer or smaller droppings — the gut is slowing down. Paired with not eating, treat it as an emergency.
Teardrop or tapered shapes — often means reduced food intake; watch appetite and weight.
Soft, clumped or squishy — usually too much fresh veg. Cut back to plain hay and water for a day.
Watery diarrhoea — never normal. See a vet promptly, it can dehydrate a small pig fast.
Strung together with hair — common in long-hairs; keep the rear trimmed and groomed.

One oddity to know: pigs eat some of their own softer droppings (caecotrophs) straight from the source. That is completely normal and how they get extra B vitamins. A quick daily glance at the cage floor is a free health check, pair it with a weekly weigh-in.
